What does BZL on jewelry mean?

This mark indicates the jeweler was able to secure a patent from the U.S. government because of unique characteristics or the possibility of copying by others even in the mass market. The patent protects the manufacturer or the designer from exact copies and helps them retain the value of their original pieces.

150 is not a recognised fraction for any of the precious metals, and if something had such a low content it would not be subject to hallmarking anyway. Unless someone has made a mistake about the figure, 150 is likely to be nothing more than a manufacturer’s mark or pattern number.

What do the markings on a piece of jewelry mean?

From metal content to manufacturer, your jewelry markings can give you a clue about the value and history of your favorite pieces. Many jewelry marks represent the metal content of the piece. This is important because silver-plated and sterling silver items look virtually identical to the untrained eye.

Aside from purity and maker’s marks, some jewelry will also bear symbols and letters, particularly hallmarks, inscribed on it. Many of these symbols and letters found on jewelry originate from assay offices. Jewelry from the United Kingdom contains a series of compulsory and optional jewelry marks set out by the countries’ assay offices.
